Yeah, the sketch tool uses the normal of the surface clicked to orient the brush when creating it.If you don't want that, currently, you can click the little cube icon in the top bar, and it'll make a 1m cube, 0 rotation. That would likely be useful.

For improvements, I could see a option/setting for conforming to the surface normal or not when creating new brushes.

That could be useful, indeed. I have some other thoughts, having worked with it more, but I'll start a new thread for that, as I don't want to derail my own thread :p
